CT Boot Camp Section 1, CT Boot Camp Questions and Answers 100% Pass A single "view" acquired during a CT scan is also called a: -Projection A CT scanner collects several projections as the tube and detectors spin around the patient. Each of these projections represent a unique view of the anatomy that is eventually compiled together to form the 3D volume of data The main difference between image production in CT compared to image production in radiography is: -Projections are compiled into ...

A new computed tomography (CT) protocol requires scanning the liver at exactly 25 seconds after initiating intravenous (IV) contrast injection. This can be accomplished by which scan timing method? correct answers Scan time delay There are several ways to time a contrast bolus. If the patient is to be scanned at a specific time after initiating contrast, the technologist will need to set the exact scan delay time. The test bolus and bolus tracking methods cannot be used to set exact times. ...
